This server collection exposes 8 tools across multiple fastmcp-based services. Tool naming is consistent and verb-forward (get_, search_, list_), descriptions are present but minimal (most 30-50 chars), and input schemas are properly typed. However, output schemas are NOT documented anywhere in the provided source, parameter descriptions are generic without constraints or examples, and error handling strategies are absent. No tool annotations (readOnlyHint, destructiveHint, idempotentHint) are present despite the READ_ONLY risk classification. The Makefile shows HTTP deployment (docker-compose with port exposure), but the actual server implementations (mcp-weather/server.py, etc.) were not provided, so per-tool definitions are partially inferred from the metadata table rather than verified against source code. This inference cap means individual tool scores cannot exceed 50 on schema/description rigor.

• Document output schemas for all tools. For get_weather, specify: {latitude: number, longitude: number, temperature: number, condition: string, humidity: number, ...}. For search/search_wikipedia, specify: {results: [{title, snippet, url}], total_count: number}. LLMs need this to plan chains.
• Expand tool descriptions to 100-150 chars. E.g., 'Get current weather conditions for a location (city name or coordinates). Returns temperature, humidity, wind, and forecast. Use when the user asks about weather.' This tells LLMs when, how, and what to expect.
• Add constraints to parameters. E.g., location: 'City name (e.g., "New York", "Paris") or lat/lon pair (e.g., "40.7128, -74.0060")'. max_results: 'integer 1 - 50 (default 10); results beyond 50 are paginated'.
• Add tool annotations to all definitions. Mark all 8 tools with readOnlyHint: true since they are all READ_ONLY per the risk field. This enables agents to reason about safety.
• Implement error handling in tool implementations and return structured error responses: {error: "location_not_found", message: "Could not geocode 'XYZ'. Try a full city name like 'New York'.", retryable: true}. Current code likely returns HTTP 400/500 with no guidance.
• Rename search → search_web and search_wikipedia → search_wikipedia to eliminate ambiguity. Or keep search for general web and add a description that says 'uses DuckDuckGo; for Wikipedia, use search_wikipedia'.
• For tools that return lists (search, search_wikipedia, list_artifact_registries), add explicit limit parameter (default 20, max 100) and return total_count and next_cursor for pagination.
